Hi,

We are using Struts2+Spring+Hibernate+JNDI in our project. In our database we have tables in different schemas. At runtime, the DB schema must be selected dynamically depending on the user selection. How can I make Spring+JNDI pick up the right DB schema or datasource at runtime?

You can have a properties file that has mapping for schema - datasource name. This mapping can be picked up statically and your connection class can use the correspoding class to return the relevant connection.

I have read something about the AbstractRoutingDataSource class. How is this used?

The AbstractRoutingDataSource  is the concrete implementation of the methodology that I described above that is available in the Spring framework. You can find more details & example with Spring on the below sites.
